To allwhom it may concern..-

Be it known that 1, JOHN K'RllClSZ, a citi zen of the United 'States of America, residing at Ghicago,'in the county of Cook and State oflllinois, have invented certain new and useful Improvements in Joiners Planes, of which the following is a'specification.

This invention relates to certain new and useful improvements in joiners planes and has particular reference to the provision of a pair of gage bars adjustably associated with the block of the plane for varying depths of cuts of the knife.

A further object of the invention embodies in a joiners plane of the type above set forth, the provision of a laterally adjustable side bar or gage for determining the position of a groove or channel relative to the edge of the article being grooved.

lVith the above objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the appended claim.

In the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views:

Fig. 1 is a side elevational view partly shown in section of a joiners plane constructed in accordance with the present invention showing the adjusting screws for shifting the gage bars relative to the cutting blade,

Fig. 2 is a top plan view of the plane showing the adjusting and clamping screws associated with the laterally shiftable gage bar.

Fig. 3 is a crosssectional view taken on line III- 111 of Fig. 2 showing the internally threaded sleeve bearing for the adjusting screw of one of the gage bars, and

Figs. 4, 5, 6 and 7 show fragmentary plan iews of the cutting ends of various types of blades.

The invention referring to a joiners plane.

designed for forming-a groove or channel in various kinds of woodwork, embodies a main body portion in the form of an elongated rectangular block 1 having a centrally positioned. slotted ope upper overhanging shoulders3 for there iception of a cutting blade and wedge retaining block. The lower 'side of theblock 1,

. as shown 1n Figs. 1 and 3, is longitudinally slotted as in 4" for the reception of gageplates positioned at opposite! sides 'of the central opening 2. i '2 eas plat s 5 a tli teb mount in the slots 1 for varying the" depth of cuts of the blade secured within the opening 2, each block 5 receiving the lower ends of adjusting screws 6 swivelly retained therein by set screws 7, the adjusting screws 6 extending vertically through the block into ning 2 provided '55 internally threaded sleeves 8 countersunk.

within the block. The outer side wall of the block 1 is suitably slotted as at 7 for permitting ready access to certain ones of the set screws 7.

As shown in Figs. 1 and 2, the cutting blade 9 having a lower cutting edge 10 is positioned in the central opening 2 and rests upon the rearwardly positioned inclined wall 11 of the central opening, the blade passing beneath the shoulders 3 while a wedge block 12 interposed upon the cutting blade engages the shoulders 3 wedging the blade to the block 1. a

A lateral gage bar 13 is associated with the block 1, being of reversed L-shaped formation having a lower leg 14 extending beneath and towards the block 1. Screw bolts 15 having operating heads 16 freely extend through the vertical leg of the lateral gage bar 13 and are threaded into openings provided in the block 1 while position retaining screws 17 having operating heads 18 are threaded through the block 1 with the ends thereof freely engaging the lateral gage bar 13 shown in Fig. 2 to hold the gage bar rigidly positioned relative to the block 1'.

Asshown in Figs. l to 7, various types of cutting blades may be employed, Figs. 4 and 5 showing cutting planes 19 and 20 especially employed in the construction of molding strips, Fig. 6 a triangular point 21 while Fig. 7 shows a curved or oval point 22.

From the above detailed description of the device it" is believed that the construction and operation will now be at once apparentit being noted that the blade 9 is anchored in the block 1 by the wedge block 12 engaging the shoulders 3 of the opening 2 and forcing the blade into frictional engagement with the inclined wall 11 of said opening,

while the adjusting; screws 6 regulate the depth of cuts of the cutting ends of the different blades 9. stood that the forward and rear gage plates, or blocks 5, are adapted to engage within the groove being cut, the depth of the'finished groove being equal to the width of the protruding portion of the said blocks The laterally adjustable gage bar 13 may be shifted to vary the distance of the cut groove from the adjacent edge of the article, the laterally adjusting gage bar being maintained in its set position'by the screws 17.

While there are herein shown and described the preferred embodiments of my invention,

it is nevertheless to be understood that vari-' ous forms, modifications and arrangements of the partsmay be made without departing It will be readily under-' from the spirit and as claimed.

Having thus describedthe inventiomwhat I claim as new is a j 1 In adevice of the class described, a body member, a cutting blade detachably received scope of the invention .within said body member gage plates loosely received within grooves formed in the forward and rearward portlons of the said body member at each slde of the sald cuttingv blade, and means for adjusting the position a of the gage plates within their respective JOHN KRECISZ.

grooves, said means comprising vertically
